The report said that 20 of 23 federally funded centers contacted by staff investigators requesting information about an unintended pregnancy were told false or misleading information about the potential risks of an abortion.

The pregnancy resource centers, which are often affiliated with antiabortion religious groups, have received about $30 million in federal money since 2001, according to the report, requested by Rep. Henry A. Waxman (D-Calif.). The report concluded that the exaggerations "may be effective in frightening pregnant teenagers and women and discouraging abortion. But it denies the teenagers and women vital health information, prevents them from making an informed decision, and is not an accepted public health practice."
